IMPROVED VELOCIIPEIDE.

The Schedule referred to in these Let ers Patent and making part of thesame.

To all whom t ina/y concern Beit known that we, (l. J. Dorr and Ani-nenS. DCKRvSON, of 'Vashington, in the county of Washington, and Districtof Columbia, have invented a new and useful Improvement in Velccipedes;and we do hereby declare that the following is a full, clear, and exactdescription of the saine, reference 1oeing had to the annexed drawings,making part ci this speciiication, in which- Figure 1 is a tcp or planview oi' our velocipede, and

Figure 2 is a longitudinal vertical section on line x a: of iig. 1.

Corresponding letters refer to corresponlling parts in both igures.

This invention relates to an improvement in that class of devicesdenominated three-wheeled velocipedes3 and It consists in thecombination and arrangement of the part-s of which it is composed, aswill be more fully described hereafter.

A, in the drawings, represents a portion ofthe framework of the machine,the rear endsgof which are attached tothe rear axles B, from which partit extends forward for any required distance, when it is so bent as toext-end transversely across the machine. A

B represents the rear axle, which is of the curved form shown in fig. l.

To this axle the two rear wheels ofthe machine are fitted. v

C O represent 'the wheels above alluded to, and

D represents the forward and guide or steeringwheel. p

E represents an axle, which has its bearings in th front, ends of theframe K, and to which the guidewheel is attached.

F F represent cranks, which are secured to the ends of shaft, or axle F,as clearly shown in iig. l.

G Grepresent connecting-rods, which extend from cranks F F to the upperand. lower ends of lever H, and are for the purpose of communicating themotion of such lever to the .cra-nhs, i'or propelling the device.

H represents a jointed leve-r, whiclnis pivoted to the spring-bars 1 I,ata-point just above the joint in the saine. The upper end is providedwith handles on either side thereof, and also with the means ofattaching to the'same, the connecting-rod G, which extends from thenceto crank F'.

The lower arm of this lever is jointed to the arm above described, itslower end being provided with projections, upon which the operator canplace his feet when operating the machine, and it is also provided withthe means of attaching thereto the connectingrod G, which leadstherefrom to crank F of the driving-shaft F.

l I represent spring-bars, which are attached to the end of frame K, infront of the bearing of shaft E, in

order that as much as possible of the weight of the operator may bethrown upon the drivingewheei of the machine. From the point of junctionwith the frame K, these bars extend, in an inclined direction, to apoint in the rear of the jointed lever, suihciently great to secure thesemicircular plate L, which joins their rear ends together.

'K represents a frame, or yoke, which is pivoted centrally to the frontend of frame A, so that as the guidewheel is turned, to give directionto the machine, this frame may turn with it. In the forward ends of thisframe are secured the boxes which hold the journals of' the driving andguide-wheel.

L' represents a plate, of metal, which is secured to the rear end of thespring-bars, and which unites them together. This plate also serves as aseat for the op erator, or as a device to which such seatV may beattached, and ais' as a support for the series of sheaves, or wheelsaround which the guiding or steering-rope passes.

M M' M?t represent wheels, or sheaves, around which the rope, or chainwhich controls thedirection of the machine passes. These sheaves areprovided with a groove in their peripheries, for the rope, or chain tolie in.

It will Vhe observed that the wheel h is larger in diameter than theremaining ones, and that it is provided with a handle, and also that therope, or chain passes .entirely around it.

This arrangement is for the purpose of causing it to be used as themeans of giving direction to the machine by being manipulated by theoperator, as he sits upon his scat, he using one oi' his hands for thatpurpose, while aiding in propelling the machine with the other; and atthe same time he is enabled to apply a considerable amount of power bymeans of the lower arms of lever H and rod G, which may be operated withhis feet. y

N representsa rope, or chain, which is to be secured to the staples a c,fixed in the frame A, it passing cntirely around wheel M", and behind oroutside of wheels M and M', as clearly shown in fig. l.

` Having thus described our invention,

What we claim, and desire to secure by Letters The arrangement of thecranks F F', connectingrods G G', and jointed lever H, -with referenceto the steering-apparatus, substantially as and for the purposespecified.

In testimony whereof, we have signed our names to this specication, inthe presence of two subscribing witnesses.
